I'm using MobileSheets 4.1.7 just a few weeks but now I get a nagging advertise requesting to buy the MS pro release. The Advertise contains additional information in german but I do not undertand it inspite of that I am german.
Is it possible to get rid of this advertise?
Yes - buy the Pro version
.
Seriously, do buy it, there have been massive improvements in all areas and it's worth every penny/cent being asked and the version you have is no longer being supported. If I can't convince you, download the free version (it's the one with the blue icon) and try it for yourself
Check the checkbox in the bottom left of the dialog to have it never displayed again. I'm going to remove the notice in the next update as well.
